Japan's Strategic Culture: Security Identity in a Fourth Modern Incarnation?

摘要

Japan has shown three distinct strategic cultures since its emergence as a modern state in the 19th century: isolationist and non-military, militarist, and post-World War II strategic culture characterized by great reluctance to use military power abroad, even in collective self-defence. This article examines Japan's strategic culture and the potential for a fourth distinct strategic culture through the broader framework of security identity, arguing that this is evolving but has not changed as much as one might expect due to institutionalized antimilitar-ism and political support for the security practices it has engendered. Contemporary Japanese strategic culture can be understood through debates over recent Japanese security policy as well as actual changes in security practice. Domestic politics and a changing international environment are likely to lead Japan to a somewhat more active military role in the near term, but an analysis based on the dynamics of Japan's dominant security identity suggests that its strategic culture will continue to show a reluctance to use or develop military power beyond very limited scenarios, despite vocal efforts by some political actors to increase military activity abroad.
